The fastest way to uninstall Microsoft Office
The simplest method is to use Windows' built-in uninstall tool or macOS's removal process, which removes Office programs and most related files in one step. On Windows, go to Settings > Apps > Apps & features, search for "Microsoft Office", select it, and click Uninstall. On Mac, open Applications, find Microsoft Office apps, drag them to Trash, then empty Trash. This removes the programs themselves but may leave behind some cached files and preferences.
If you want a more thorough removal that clears leftover files, you can use Microsoft's official removal tool or manually delete remaining folders. The choice depends on whether you plan to reinstall Office later or want the computer completely clear of it.
Key Takeaways
- Windows users can uninstall Office through Settings > Apps > Apps & features by searching for Microsoft Office and clicking Uninstall.
- Mac users should drag Microsoft Office applications to Trash from the Applications folder, then empty Trash.
- Microsoft provides an official removal tool for Windows that deletes Office files more thoroughly than the standard uninstall.
- Leftover cache files and preferences may remain after a standard uninstall, but they take minimal storage space and won't interfere with other programs.
- If you plan to reinstall Office later, a standard uninstall is sufficient; only use the thorough removal if you want the computer completely clear of Office traces.
Windows: Using the standard uninstall method
Open Settings by pressing Windows key + I, or click the Start button and type "Settings". Navigate to Apps, then select Apps & features from the left sidebar. Scroll through the list or use the search box at the top to find "Microsoft Office" or individual Office programs like "Microsoft Word" or "Microsoft Excel". Click the program name, then click the Uninstall button that appears. Windows will prompt you to confirm; click Uninstall again.
The uninstall process typically takes two to five minutes. Windows will remove the Office programs and their core files. You may be asked to restart your computer when finished. After restart, Office programs will no longer appear in your Start menu or applications list.
Windows: Using Microsoft's removal tool for complete cleanup
If the standard uninstall leaves behind files you want removed, Microsoft provides the Support and Recovery Assistant tool. Download it from Microsoft's website by searching "Microsoft Support and Recovery Assistant". Run the installer, open the tool, and select "I want to uninstall Office". The tool will scan your computer, identify all Office-related files and registry entries, and remove them.
This method is more thorough than the standard uninstall but takes longer—typically 10 to 20 minutes depending on how much Office software was installed. Use this only if you want Office completely removed, including cache files and preferences. If you think you might reinstall Office later, the standard uninstall is usually sufficient.
Mac: Removing Office applications and related files
Open Finder and navigate to Applications. Look for Microsoft Office programs: Word, Excel, PowerPoint, Outlook, and OneNote appear as individual apps. Select each one, press Command + Delete, or right-click and choose Move to Trash. After removing all Office apps, empty Trash by right-clicking the Trash icon in the Dock and selecting Empty Trash.
For a more complete removal on Mac, you can also delete the Office preferences folder. Open Finder, press Command + Shift + G to open "Go to Folder", type ~/Library/Preferences, and look for files starting with "com.microsoft". Move these to Trash as well. Then empty Trash again. This removes settings and cache files that the standard removal leaves behind.
What gets left behind after uninstall
Standard uninstalls typically leave behind cache files, temporary files, and user preferences. On Windows, these are usually stored in hidden folders like AppData\Local and AppData\Roaming. On Mac, they live in ~/Library/Caches and ~/Library/Preferences. These leftover files are small—usually under 500 MB total—and do not interfere with other programs or slow down your computer.
You do not need to manually delete these files unless you want the computer completely clear of Office traces. If you plan to reinstall Office later, leaving them behind can actually speed up reinstallation because Office will recognize some of your previous settings. If you want them gone, the Microsoft removal tool on Windows or the manual Library deletion on Mac will handle it.
Reinstalling Office after removal
If you uninstall Office using the standard method and later decide to reinstall it, you can download Office from Microsoft's website or use an installation disc if you have one. Sign in with the Microsoft account associated with your Office license, and the installation will proceed normally. If you used the thorough removal tool, reinstallation works the same way—there is no difference in the process.
Keep your product key or the email associated with your Microsoft account handy before you uninstall, so you can reinstall without searching for it later. If Office came with your computer or was part of a subscription, check your account settings to confirm the license is still active.
Removing Office without losing your documents
Uninstalling Office does not delete your documents. Word files (.docx), Excel spreadsheets (.xlsx), PowerPoint presentations (.pptx), and other Office documents remain on your computer in whatever folder you saved them to. You can still open and view these files after Office is removed—Windows and Mac will offer to open them with alternative programs like Google Docs, LibreOffice, or OnlyOffice.
Before uninstalling, make sure you know where your important Office files are stored. If they are in OneDrive or another cloud service, they will remain accessible through the web or through the cloud service's app. If they are only on your computer's hard drive, consider backing them up to an external drive or cloud storage before removing Office, just as a precaution.
Frequently Asked Questions
Will uninstalling Office remove my Word documents and Excel files?
No. Uninstalling Office removes only the programs themselves, not the documents you created with them. Your .docx, .xlsx, and other Office files stay on your computer in the folders where you saved them. You can still open these files with other programs like Google Docs or LibreOffice after Office is removed.
Do I need to restart my computer after uninstalling Office?
Windows usually prompts you to restart, and it is a good idea to do so to ensure all Office processes stop running. Mac does not typically require a restart, but restarting does not hurt. If you skip the restart and Office programs still appear in your applications list, restart and try again.
Can I uninstall just one Office program like Word, or do I have to remove all of Office?
You can uninstall individual programs. In Windows Settings > Apps & features, search for "Microsoft Word" or "Microsoft Excel" separately and uninstall each one you do not want. On Mac, you can drag individual apps to Trash. However, if Office came as a suite package, uninstalling one program sometimes uninstalls others as well.
What is the difference between the standard uninstall and Microsoft's removal tool?
The standard uninstall removes Office programs and their main files. Microsoft's removal tool goes further and deletes cache files, preferences, and registry entries that the standard uninstall leaves behind. Use the removal tool only if you want Office completely gone; otherwise, the standard uninstall is faster and sufficient.
If I uninstall Office, can I still open .docx and .xlsx files?
Yes. After uninstalling Office, you can still open Word and Excel files with other programs like Google Docs, LibreOffice, Microsoft 365 online, or Apple Pages. Windows and Mac will ask you to choose a program the first time you open an Office file after uninstalling. You can also right-click the file, select "Open with", and pick an alternative program.
